Mortal Kombat 1 was a critical success upon its launch last September, but has since become controversial with many fans. The game feels good to play and looks great on most platforms, but it is plagued with expensive microtransactions and balance issues. Kameo Fighters, a newly added assist mechanic, have transformed the series. Concerns about the impact of Kameo Fighters on Mortal Kombat 1's balance are among the hottest points of discourse around it right now, but their addition runs the risk of impacting other elements of the game. The inclusion of assist fighters could harm one of the series at large's greatest assets: its roster.
